1.1×1.1×1m Electrical Heating Tinning Furnace | Industrial Bushing & Non-Ferrous Parts Surface Tinning System

1.1×1.1×1m Electrical Heating Tinning Furnace | Industrial Bushing & Non-Ferrous Parts Surface Tinning System

I. Product Overview

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. proudly presents the WDL-50 (1.1×1.1×1m) Electrical Heating Tinning Furnace, a premier hot-dip tinning solution custom-engineered for industrial bearings, bush sleeves, Babbitt alloy segments, and precision non-ferrous metal parts. Driven by a 50kW peripheral plate-heating array and precise Silicon Controlled Rectifier (SCR) power modulation, this heavy-duty system features a 30mm ultra-thick Pure Iron Pot capable of managing consistent thermal pools up to 450°C. With an exceptional temperature control accuracy of ±1°C, it delivers a uniform, bubble-free tin finish that elevates component surface durability.

II. Industry Challenges & Causes

• Problem: Fatal Muffle Corroding and Premature Leaks Caused by Hot Liquid Tin.

  Cause: High Dissolution Rate of Liquid Metal. Under cyclic high temperatures, molten tin actively dissolves chromium and nickel elements within standard stainless steel, creating extreme thinning and eventual muffle perforation.

• Problem: Excessive Dross Generation and Variable Layer Thickness.

  Cause: Lagging Conduction and Coarse Thermal Gradients. Inefficient element placement combined with standard on/off relay switches leads to dramatic temperature fluctuations and cold layers, accelerating costly tin oxidation.

• Problem: Tangled Site Interconnections and Prolonged Installation Timelines.

  Cause: Unstandardized Module Integration. Fragmented layouts without built-in cabling systems leave factories struggling with complicated wiring, increasing labor costs and grounding risks.

III. Our Solution

• Robust 30mm Pure Iron Pot Engineering: The 1.1×1.1×1m melting reservoir is cast entirely from 30mm thick high-purity pure iron, providing maximum erosion resistance against aggressive liquid tin.

• 50kW All-Around Wrap-Around Heating: Outfitted with 4 heavy-duty plate-type heating wires (12.5kW each) wrapping the pot's exterior, offering a grand 1200×850mm active thermal boundary with a reliable Y-type electrical grid connection.

• Flawless ±1°C SCR Current Tuning: Employs dual-endpoint thermocouple tracking married directly to an advanced SCR power regulator, achieving stepless micro-ampere current smoothing to enforce a strict ±1°C thermal balance.

• Visualized Command Station: Outfitted with a premium 10-inch Weinview industrial touchscreen interface and a standalone power cabinet (approx. 1500×600×500mm), ensuring fully traceable process variables.

IV. Technical Specifications

V. How To Choose (Selection Guide)

1. Validate Process Immersion Volume: The net interior volume of the iron pot is 1100×1100×1000mm. Calculate your component dimensions alongside your transport hangers or mechanical crane baskets to ensure parts submerge smoothly beneath the liquid level.

2. Facility Facility Compatibility: Your facility must provide a stable 380V three-phase grid matched to the full electrical load. Standard lifting gears (cranes/forklifts) and manual welding tools should be ready during the initial unloading sequence.

3. Floor Area Asset Allocation: Secure a dedicated storage bay and ensure all plant emergency exit lanes remain unobstructed. It is highly recommended to station dry-chemical fire extinguishers adjacent to the main control panel for operational safety.

VI. FAQ

• Q: Why is a "30mm Pure Iron Pot" specified instead of standard SUS304 or SUS316 stainless steel?

  A: Molten tin has a strong chemical affinity for alloys like nickel and chromium, which are the main ingredients of stainless steel. An industrial stainless steel pot will erode and fail rapidly. High-purity pure iron holds virtually zero solubility in molten tin. Combined with the 30mm thick walls, it extends the hardware lifecycle dramatically.

• Q: Can the furnace still run if one of the plate heating elements fails?

  A: Yes. The system splits the 50kW thermal array across 4 distinct peripheral plate zones managed via the SCR. If one block breaks down, the other three will compensate to maintain holding temperatures, allowing maintenance teams to schedule swap outs without interrupting the immediate work shift.
